GEARING.

Specification of Letters Patent.

Patented Apr. 2a, 1917.

Application filed September 28, 1916. Serial No. 122,747.

To all whom it may concern:

Be it known that 1, ROBERT \VARRINER, a citizen of the United States, residing at Quincy, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Gearing, of which the following is a specification.

This invention relates to an improved construction of gearing.

The object of the invention is to provide a gear which is strong and durable and easy to manufacture.

The invention consists in a gear constructed as hereinafter set forth in the specifica tion and particularly as pointed out in the claims.

Referring to the drawings:

Figure l is a side elevation of a portion of a gear constructed in accordance with my invention.

Fig. 2 is a sectional elevation taken on line 22 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 is the central body portion of the gear and 6 the peripheral portion thereof. The central body portion consists of a hub 7, a flange 8 and web 9 and said body portion has provided upon its periphery a positioning and locking rib 10. This rib preferably, although not necessarily, extends entirely around the periphery of the body portion 5 and is located between and at a substantial distance from the two opposite sides of said body portion.

The peripheral portion 6 consists of a plurality of gear rings 11, a plurality of said rings being located on each side of the rib 10. The central gear ring 12 encircles the rib 10.

The gear rings are clamped together and to the body portion 5 by bolts 13 which eX- tend through said gear rings andforce them against each other and toward and against the rib 10. Thus said rings are clamped together and also are prevented from motion laterally thereof upon the body portion 5 by reason ,of the positioning and locking rib 10 which holds said rings against any lateral movement. Said rings are locked against circumferential displacement upon the body portion 5 by a key 1-1.

The central portion of the gear can be made of iron or steel as desired, while the gear rings forming the peripheral portion can be made of steel rolled and machined to fit snugly upon the periphery of the flange 8 and the rlb 10.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:

A gear having, in combination, a cylindrical body portion, a rib on the periphery of said body port-ion located between and at a substantial distance from the opposite sides of said body portion, a peripheral portion, said peripheral portion comprising a plurality of rings keyed to said body portion on opposite sides of said rib, a gear ring encircling said rib and bolts extending through said first mentioned gear rings and clamping them to said rib.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

ROBERT XVARRINEB.
